Original application March 31, .1944, Serial No. 528,987, new Patent No.$474,673; dated June Divided and this 19%, Serial No. 95,408

My invention. relates ales and tips for burning and welding torches and,being a division from my application filed March- 31... 1944:, SerialNo. 528,987., now become Patent Number angers, granted June 28, 1949. Anobject of: the. present invention. is to provide a collet regulator ofnovel construction for the. bore of a burning and/or welding torch whichvregulator is movedtowards. the closed position a; pushing on thrustaction. of the regulator relative to the head section of the nozzle.

Another object. oi the invention is to simplify the construction ofarticles of the class specified whereby they will be exceedinglyefficient in oper ation although relatively inexpensive in the cost ofmanufacture.

A further object of this invention is to provide a sectional nozzle inwhich each section may be drilled separately to facilitate manufactureand reduce costs.

With the above and other objects in view this invention consists of thedetails of construction and combination of elements hereinafter setforth and then designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same I will describeits construction in detail referring by numerals to the accompanyingdrawing forming a part hereof, in which:

Fig. l is a longitudinal sectional view of the nozzle shell withregulator elements in elevation. Fig. 2 is a bottom or inner end viewthereof.

Fig. 3 is a longitudinal sectional view of the regulator collet.

Fig. 4 is a similar view of the adjusting member.

Fig. 5 is an upper or outer end view of the regulator collet.

In carrying out my invention as herein embodied, 6 represents atwo-piece or sectional nozzle for burning and welding torches,comprising a body or inner member or section 1 and a head or outermember or section 8, connected together by a threaded joint. Thisconstruction makes it easy to form the various types of bores,passageways, openings and recesses with short boring operations andlikewise makes it easy to reach certain locations for countersinking,finishing and the like, thus facilitating the manufacture and reducingthe cost thereof.

The nozzle body I is provided with a reduced externally threaded portionor shank 9 adapted to be screwed into a torch head, and a noncircularportion for the reception of a wrench 4;Claims.. (01.158. 27. 1).

or other tool. Abore H is. formed in the body section 1 from end to.end, including the shank, and said body'section is internally threadedfor at slgort distance at its inner end asv indicated a l Anexternallythreaded neck I 3 is formed at the inner end of the body section I andprovides a shoulder 14 and said neck has a flat end to provide a flat.seat l5. This neck 53 is projected into the threaded socket 16 at. theinner end of the nozzle head sectionfi for joining the twov sectionstogether with the shoulder 94 abuttin the inner end of said head section8 and the seat l5 engaging the shoulder l7, produced by the formation ofthe socket, to provide a gas tight joint. A bore iii in the head section8 runs from end to end of the said head section and is slightly largerthan the bore I! so as to expose a portion of the seat [5 within thebore l8 when the two sections are joined together. The outer end ofsaidbore l8 terminates in a cone shaped or converging internal seat l9.

The outer end of said head section is externally threaded at 20 toreceive a demountable tip 2| and the inner end of said head section hasa non-circular portion 22 for the reception of a wrench or other tool.

The tip 2! is of non-circular configuration on the exterior whereby itmay be readily rotated and is internally threaded for mounting andadjustment on the threaded end of the head section of a nozzle. Thisparticular tip has a tapered hole 23 in the center of its top or endwall, and because of the shape of the hole 23 said tip 2| preferably isused with liquified gas, such as propane, butane and the like.

A regulator '24 includes two separate but coacting elements, one asleeve 25, Fig. 3, and the other an adjusting member 26, Fig. 4. Thesleeve 25 has its upper or outer portion slit longitudinally as at 21and provided with a cone shaped end 28 to fit the conical seat l9. Thesegments produced by the slits are contracted as the sleeve 25 is pushedoutward and due to the inherent resiliency they will spring apart orexpand as the sleeve is permitted to or actually is moved inward. Thesleeve bore 29 runs completely through it from end to end.

The adjusting member 26 includes an externally threaded shank ill and aknurled head 3| for readily screwing said shank in and out or thethreaded portion of the bore ll of the body section 1 for setting saidadjusting member. After the desired setting has been obtained a lock nut32 on the threaded shank is screwed down tight against the seat l5. Nowwhen the head and body sections of the nozzle are screwed together, theadjusting member 26 will engage the inner end of the sleeve and forcethe latter outwardly so that the conical end 28 will slide along thecone shaped seat [9 apredetermined distance which will regulate the sizeof the sleeve bore at its outer end.

The adjusting member 26 has a bore 33 running from end to end thereof topermit passage tion, a socket at the inner end of said head section, abody section having a bore therethrough from end to end thereof andinteriorly threaded at the inner end, a neck carried by said bodysection for engagement with the socket end of the head section todetachably connect said sections, a sleeve having a conical outer end tofit,

the conical seat and slit for a distance from said outer endlongitudinally inwardly, a hollow adjusting member externally threadedand adjustably screwed into the inner end of the bore of the bodysection to contact the sleeve for pushing 4 the latter outwardly as thesections are connected together, and a lock nut on the adjusting memberengaging the inner end of the body section.

2. The nozzle of claim 1, wherein the outer end of the head section isthreaded, in combination with a tip removably mounted on said threadedouter end.

3. The nozzle of claim 1, wherein the outer end of the head section isprovided with means for attachment thereto of any one of a number ofinterchangeable tips, the mounted tip coacting with the terminal end ofthe conical portion of the sleeve.

4. In a nozzle for gas burning apparatus including a body section and ahead section detachably connected together and each having a boretherethrough from end to end thereof, said head section having a coneshaped seat on the interior of the outer end thereof, a regulator withinsaid nozzle and comprising a sleeve having a cone shaped outer end toengage the seat and slit longitudinally inwardly a distance sufficientto produce several segments having an inherent resiliency 'to normallyseparate them, and a hollow adjusting member threadedly connected to thebody section for adjusting said member longitudinally, said membercoacting with thesleeve to push th latter outwardly when the sectionsare connected together and thereby contracting the segments.
